OpenAI stages GPT-6 Astra model on API, hinting at imminent release despite internal naming debate
Multiple developer reports indicate OpenAI has staged model slugs "gpt-6-astra" and "gpt-6-astra-aeon" on its APIs and Codex platform, returning a gated 404 error distinct from fake model names. This technical evidence suggests preparation for a new model release. However, a report from The Information states OpenAI internally considered naming Astra "GPT-6" but decided against it, revealing internal branding deliberations.

OpenAI considered naming Astra 'GPT-6' but decided against it, per The Information
According to a report from The Information, OpenAI internally considered naming its AI model Astra 'GPT-6' but ultimately decided against using that designation. The decision reflects internal deliberations about product branding and model naming strategy at the leading AI research organization. The report, cited by analyst Rohan Paul on X, highlights that while the GPT-6 label was considered, it was not adopted for the Astra model. The exact reasons for passing on the name were not detailed in the post. This development is notable as it provides insight into OpenAI's naming conventions and product planning, which are closely watched by the AI industry and investors. The Information's report adds to ongoing discussions about how AI companies brand their successive model generations.
OpenAI briefly publishes then removes GPT-6 Astra blog post with benchmark scores
A post on X claims that OpenAI briefly published a blog post for GPT-6 Astra, a new AI model, before quickly taking it down. The author states that the full benchmark table for the model was already captured and shared online, describing the scores as 'insane'. The post includes a link to the leaked benchmark data. This incident suggests an accidental early release of information about OpenAI's next-generation AI model, generating significant attention and speculation about its capabilities. The exact benchmarks and scores are not detailed in the post itself but are referenced as being available via the linked content.
Two new GPT-6 model IDs, gpt-6-astra and gpt-6-astra-aeon, appear in Codex
A post on X by user DanDr1s reports that two new GPT-6 model IDs have appeared in Codex, OpenAI's development platform. The IDs are gpt-6-astra and gpt-6-astra-aeon. The poster speculates that gpt-6-astra-aeon likely represents a higher-effort, long-horizon variant, possibly built for autonomous multi-agent work. This suggests ongoing development of next-generation AI models by OpenAI, with potential applications in complex, autonomous systems. The appearance of these IDs indicates internal testing or preparation for future releases, though no official announcement has been made by OpenAI.

OpenAI stages gpt-6-astra model on API, returns gated 404 response
A new AI model named 'gpt-6-astra' has apparently been staged on the OpenAI API, according to a post by user ChrisGPT on X. The post notes that while completely fake model names return a flat 400 error, querying 'gpt-6-astra' returns a 404 error, which is the same gated response previously observed for the model 'gpt-5.6-cyber'. This suggests that OpenAI has prepared the model name on its backend, though it is not yet publicly accessible. The finding was first reported by user @mrfanduu. The post does not provide further details on the model's capabilities, release date, or intended use.
OpenAI GPT-6-Astra model slug spotted on APIs, hinting at imminent release
A post from testingcatalog on X reports that the model slug for OpenAI's GPT-6-Astra has been spotted on the APIs. The post suggests that if the model is actually released tomorrow, it would be a huge week. The post includes a link for routing first. This indicates potential imminent availability of a new AI model from OpenAI, building on speculation about the next generation of their language models.
GPT-6 Astra model staged on OpenAI API, developer reports
A developer has reported that a new AI model named "gpt-6-astra" has been staged on the OpenAI Responses API. The claim is based on a technical observation: querying the API for "gpt-6-astra" returns a 404 Not Found error, while garbage or non-existent model slugs return a 400 Bad Request error. This same 404 response is also returned for "5.6 Cyber", a model known to exist. The developer notes a similar quirk existed in the Bedrock API prior to the launch of the Fable 5.1 model. This evidence suggests that OpenAI is preparing to release a new model, potentially named GPT-6 Astra, though no official announcement has been made. The post provides a technical method for detecting pre-release models based on distinct API error responses.
